Here's an iRule to accomplish it. 


when HTTP_REQUEST {
   if { [HTTP::host] eq "www.mysite.com" and [HTTP::uri] starts_with "/admin" and ![class match [IP::client_addr] eq inside_addresses] } {
     discard }}

This requires that you create an address-type "datagroup" containing the IPs you want to allow. Let me know if you have any issues.
